Go Daddy is blocking companies from harvesting its DNS records, the company has confirmed.

CTO Dave Koopman denied that Go Daddy has a “DNS Blackouts” policy, but confirmed that it has banned certain IP addresses from doing DNS queries for its customers’ domains. He wrote:

The rumor about “DNS Blackouts” was started by someone using Go Daddy servers to cache all Go Daddy DNS records on his personal servers for financial gain.

Back to our previous example of 100 queries a day. Instead of one person accessing 100 domain names, this individual was attempting to download tens of millions of Go Daddy DNS records – twice daily. While his behavior did not cause any system issues, we felt it best to revoke access to the offending IPs.
